Yes when   surgery is underwent by a good orthopedic surgeon results are great . physiotherapy by a professional physiotherapist in the long term will help u achieve all your goals.but it vl take time.mere delay in surgery if indicated and bearing pain should not lead into a arthritic knee joint .so early intervention can be the key.though Rehabilitation will be a long term process to be focused on.till then do frequent icing for 20 mins.give compression and elevation for your lower limb.
